Dreadnoughtus, the largest dinosaur whose size can be calculated reliably. A very complete fossil of this sauropod was unearthed in 2009. In life Dreadnoughtus was 26 metres (85 feet) long and weighed about 65 tons. Encyclopædia Britannica, Inc.
Giganotosaurus had a much weaker bite of just 6,000 Newtons, but it had 76 sharp, serrated teeth ready to harm an enemy. The T-Rex has the advantage in terms of bite force and teeth, and it's not even close.
The speediest dinosaurs were the ostrich mimic ornithomimids, such as Dromiceiomimus, which could probably run at speeds of up to 60 kilometres per hour.
We've seen some scary dinosaurs before, the T-Rex, Utahraptor and Jeholopterus all come to mind, but the newly discovered Heterodontosaur may be the scariest of all. It was a small, fanged dinosaur species that wandered around the toes of other dinosaurs.
Let us take a look at these dinosaurs and what about them made them slower than other dinosaurs.
Nyasasaurus Parringtoni is believed to be the earliest dinosaur to have ever lived on Earth. It predates all other dinosaurs by more than 10 million years.
A Triceratops may have been the last dinosaur standing, according to a new study that determined a fossil from Montana's Hell Creek Formation is "the youngest dinosaur known to science."
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Nigersaurus -- so named because it was discovered in Niger -- had the long neck of a Diplodocus and up to 1,000 teeth in its intricate jaws, Sereno, of the University of Chicago, said on Monday. The bones of the 1,000-toothed "lawnmower" which scythed across west Africa were found first by a French researcher.
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
On our first day, we found bones of the long-necked dinosaur Nigersaurus. Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago. This sauropod (long-necked dinosaur) has an unusual skull containing as many as 500 slender teeth.
|Nigersaurus Temporal range: Aptian - Albian|
Leech has 32 brains. A leech's internal structure is segregated into 32 separate segments, and each of these segments has its own brain. Leech is an annelid.
the blue whale
The largest animal poop in the natural world belongs to that of the blue whale. Each bowel movement of these enormous, magnificent creatures can be in excess of several hundred liters of excrement at a time!
Because the anteater has no teeth, their stomach does all the chewing. It has hardened folds that rub against each other and grind insects down for digestion. To help with this, anteaters swallow sand and small pebbles along with their food.
Snails: Even though their mouths are no larger than the head of a pin, they can have over 25,000 teeth over a lifetime – which are located on the tongue and continually lost and replaced like a shark!
Other animals naturally have no tongues, such as sea stars, sea urchins and other echinoderms, as well as crustaceans, says Chris Mah via email.
The tiny kangaroo rat located in the south-western deserts of the United States does not drink water for its whole lifespan. Kangaroo rats represent an integral part of desert life.
